I was looking at Chistensen Arms web site and they offer to put their barrels on any action stocked gun you supply. They will build a custom gun from scratch using, Remington, Winchester, Browning, Sako, or Weatherby. Now I am not planning on or have the money to have a custom gun built. But if you could or did already do it what action would have it built on and why? Also what action is the strongest?
